Comment(by StephenBlackheath):

 In case it's helpful, with this patch I am suggesting in this ticket...

 ...if it isn't applied, then this is what I get (latest head, git hash

 }}}

 So, arm-ldu-linux-gnueabi-ghc-pkg is a dangling symlink.

 If I then apply the patch, then the wrapper arm-ldu-linux-gnueabi-ghc-
 pkg-7.7.20130203 gets installed and the problem goes away.
